|Success in the 3-D bioprinting of cartilage|
Added: 28.04.2017 20:23 | 0 views | 0 comments
A team of researchers has managed to generate cartilage tissue by printing stem cells using a 3-D-bioprinter. The fact that the stem cells survived being printed in this manner is a success in itself. In addition, the research team was able to influence the cells to multiply and differentiate to form chondrocytes (cartilage cells) in the printed structure.
|Single gene encourages growth of intestinal stem cells, supporting 'niche' cells, and cancer|

A gene previously identified as critical for tumor growth in many human cancers also maintains intestinal stem cells and encourages the growth of cells that support them, according to results of a study. The finding adds to evidence for the intimate link between stem cells and cancer, and advances prospects for regenerative medicine and cancer treatments.
|Stem cells edited to fight arthritis|

Using CRISPR technology, a team of researchers rewired stem cells' genetic circuits to produce an anti-inflammatory arthritis drug when the cells encounter inflammation. The technique eventually could act as a vaccine for arthritis and other chronic conditions.
|RETINOBLASTOMA RELATED1 mediates germline entry in Arabidopsis|

To produce seeds, flowering plants need to specify somatic cells to undergo meiosis. Here, we reveal a regulatory cascade that controls the entry into meiosis starting with a group of redundantly acting cyclin-dependent kinase (CDK) inhibitors of the KIP-RELATED PROTEIN (KRP) class. KRPs function by restricting CDKA;1-dependent inactivation of the Arabidopsis Retinoblastoma homolog RBR1. In rbr1 and krp triple mutants, designated meiocytes undergo several mitotic divisions, resulting in the formation of supernumerary meiocytes that give rise to multiple reproductive units per future seed. One function of RBR1 is the direct repression of the stem cell factor WUSCHEL (WUS), which ectopically accumulates in meiocytes of triple krp and rbr1 mutants. Depleting WUS in rbr1 mutants restored the formation of only a single meiocyte.
|Genes need to be screened for stem cell transplants|

As stem cell lines grow in a lab dish, they often acquire mutations in the TP53 (p53) gene, an important tumor suppressor responsible for controlling cell growth. New research findings suggest that genetic sequencing technologies should be used to screen for mutated cells in stem cell cultures, so that cultures with mutated cells can be excluded from experiments and therapies.

Stem cells extracted from baby teeth may someday regrow a lost adult tooth or offer other medical benefits, but the current research does not yet provide evidence of value.

Using human skin cells, neurobiologists have created a method to generate one of the principle cell types of the brain called microglia, which play a key role in preserving the function of neural networks and responding to injury and disease.
